A student on a raft floating behind the canoe says the canoe has NO kinetic energy.
A teacher standing on the riverbank when the canoe floats by says it has 44 joules of KE.
They're both correct.

kinetic energy is simply 1/2 *mass* velocity^2
so since you know both mass and velocity you should be able to calculate the kinetic energy.
